Technique for Fast Octaves?

I'm working on this song and it's obviously quite simple in nature but the speed on the octaves just isn't my thing. I'm not sure if I should play the note with my index finger and the octaves with my middle finder or rather the note with index and then middle-index (or index then middle) for the octaves. Any thoughts?

Sorry..thought I mentioned the song. It's YMCA by the village people. I started practicing using index-middle-index-index-middle...for note-octave-octave-note-octave. Feels OK, just needs practice obviously but I wasn't sure what everyone else does.

Is that the "pattern" you guys would follow or do you suggest something else? That seems to be the most natural to me but I'm open to suggestions. By the way, the video I watched for this is at THIS LINK . His fingers move too fast so I can't follow what he's using on his right hand.

I think slapping it would be cheating, too, wouldn't get the same tone. But if your thumb is good you could play the bottoms of the octaves with your thumb and the fast upper notes index-middle. Otherwise your proposed pattern is fine if you can get it working.

I would probably do it the way you have suggested as well because my thumb isn't that good. It would be tough for me, I may have to work on it just for that reason!

Wish I could see the video..I thought the one I posted was impressive, so I'm interested in seeing a better version. Right now I have the chorus on loop at 75% speed and am working on nailing it before I go any faster. My index and middle finger get crossed up and the fingers on my left hand have trouble during the transitions but that comes with practice I suppose. I'm going to work on isolating the parts of the song and working on them at a slower speed and then building up the whole song. Thanks for the advice and talk everyone!
